Clinical Decision-Making in Trauma Surgery: A Penetrating Junctional Injury Case Study

Prehospital Management of a Stab Wound

• 🚑 An 18-year-old male presented with a stab wound to the posterior left axillary region, with significant bleeding noted by bystanders.
• 🩸 Initial first aid included wound packing by a bystander GP and IV access by paramedics.
• 🚁 London Air Ambulance arrived, applied Seelocks gauze and a pressure dressing, and administered one unit of packed red cells, one unit of FFP, and 2 grams of TXA.
• ⏱️ The patient had a total prehospital time of 43 minutes, arriving at the Royal London Hospital with a heart rate of 110 and systolic BP > 110, despite absent radial pulses initially.

Emergency Department and Initial Surgical Assessment

• 🏥 Upon arrival, the major hemorrhage protocol was activated, releasing substantial blood products (Pack A and Pack B) with a 1:1:1 ratio of red cells, FFP, and platelets, plus cryoprecipitate.
• 🩺 The trauma team repeated the primary survey, noting reassuring hemodynamics and a well-packed wound.
• 🧠 A decision was made to proceed to CT scan for detailed anatomical assessment, rather than immediate operative exploration, due to the patient being a fluid responder.

Operative Management of Axillary Artery Injury

• 🔪 An infra-clavicular incision was made, achieving proximal and distal control of the axillary artery.
• 🛠️ A transsected axillary artery was identified and repaired primarily with proline sutures, with the packing from the posterior wound being removed after surgical hemorrhage control.
• 🩺 Post-repair, distal flow was assessed with ultrasound, showing good Doppler signals.

Controversies in Vascular Repair and Anticoagulation

• ⚖️ The use of systemic intraoperative anticoagulation in vascular trauma is debated, with guidelines suggesting a case-by-case approach, especially in patients with coagulopathy or head injuries.
• 📈 Literature shows mixed results regarding the benefit of intraoperative anticoagulation, with some studies suggesting improved outcomes and others finding no significant benefit or harm.
• 💉 Aspirin (single antiplatelet therapy) is generally recommended for vascular repairs, while the use of synthetic grafts for interposition grafts is supported by recent guidelines as potentially quicker and no worse than autologous vein, though historically controversial.

Postoperative Course and Reintervention

• 🛌 The patient was extubated and transferred to the ICU for one night, then to the trauma ward.
• ⚠️ On postoperative day two, a difficult-to-palpate radial pulse raised concern, leading to an ultrasound which showed stenosis at the site of repair.
• 🏥 The patient was returned to theater on day four for take-down of the previous repair and insertion of a short synthetic interposition graft.

Holistic Trauma Care and Rehabilitation

• 🤝 The London major trauma system emphasizes holistic care, including prehospital, ED, OR, postoperative care, rehabilitation, and secondary prevention.
• 🩹 Services like the St. Giles trauma service (violence reduction project) and the after trauma team provide crucial pastoral care, advocacy, and support for reintegration into the community for young patients with interpersonal injuries.
• 🧠 Input from the trauma psychology team is also vital, recognizing the psychological impact of traumatic events.

Key Takeaways from the Case

• ⚠️ Junctional vascular injuries carry a higher mortality risk.
• 🚁 Prehospital hemorrhage control and blood product resuscitation are critical for stabilizing patients.
• 🎯 A 1:1:1 major hemorrhage protocol is the standard for goal-driven transfusion.
• 🔬 CT trauma series can aid operative planning in fluid responders with junctional injuries.
• 🩹 Primary repair is preferred, followed by interposition grafts, with synthetic grafts being a viable option.
• 💊 Anticoagulation decisions should be individualized, and aspirin is recommended post-repair.
• ❤️ Rehabilitation and secondary prevention are essential components of trauma care to prevent readmissions.
